Summary
Saleor is an e-commerce platform. Starting in version 3.0.0 and prior to versions 3.20.108, 3.21.43, and 3.22.27, Saleor allowed authenticated staff users or Apps to upload arbitrary files, including malicious HTML and SVG files containing Javascript. Depending on the deployment strategy, these files may be served from the same domain as the dashboard without any restrictions leading to the execution of malicious scripts in the context of the user's browser. Malicious staff members could craft script injections to target other staff members, possibly stealing their access and/or refresh tokens. Users are vulnerable if they host the media files inside the same domain as the dashboard, e.g., dashboard is at `example.com/dashboard/` and media are under `example.com/media/`. They are not impact if media files are hosted in a different domain, e.g., `media.example.com`. Users are impacted if they do not return a `Content-Disposition: attachment` header for the media files. Saleor Cloud users are not impacted. This issue has been patched in versions: 3.22.27, 3.21.43, and 3.20.108. Some workarounds are available for those unable to upgrade. Configure the servers hosting the media files (e.g., CDN or reverse proxy) to return the Content-Disposition: attachment header. This instructs browsers to download the file instead of rendering them in the browser. Prevent the servers from returning HTML and SVG files. Set-up a `Content-Security-Policy` for media files, such as `Content-Security-Policy: default-src 'none'; base-uri 'none'; frame-ancestors 'none'; form-action 'none';`.

A partir de la versi\u00f3n 3.0.0 y antes de las versiones 3.20.108, 3.21.43 y 3.22.27, Saleor permit\u00eda a los usuarios de personal autenticados o a las aplicaciones (Apps) subir archivos arbitrarios, incluyendo archivos HTML y SVG maliciosos que conten\u00edan Javascript. Dependiendo de la estrategia de despliegue, estos archivos pueden ser servidos desde el mismo dominio que el panel de control sin restricciones, lo que lleva a la ejecuci\u00f3n de scripts maliciosos en el contexto del navegador del usuario. Miembros del personal maliciosos podr\u00edan crear inyecciones de scripts para atacar a otros miembros del personal, posiblemente robando sus tokens de acceso y/o de actualizaci\u00f3n. Los usuarios son vulnerables si alojan los archivos multimedia dentro del mismo dominio que el panel de control, p. ej., el panel de control est\u00e1 en \u0027example.com/dashboard/\u0027 y los medios est\u00e1n bajo \u0027example.com/media/\u0027. No tienen impacto si los archivos multimedia est\u00e1n alojados en un dominio diferente, p. ej., \u0027media.example.com\u0027. Los usuarios tienen impacto si no devuelven una cabecera \u0027Content-Disposition: attachment\u0027 para los archivos multimedia. Los usuarios de Saleor Cloud no tienen impacto. Este problema ha sido parcheado en las versiones: 3.22.27, 3.21.43 y 3.20.108. Algunas soluciones provisionales est\u00e1n disponibles para aquellos que no pueden actualizar. Configure los servidores que alojan los archivos multimedia (p. ej., CDN o proxy inverso) para que devuelvan la cabecera Content-Disposition: attachment. Esto indica a los navegadores que descarguen el archivo en lugar de renderizarlo en el navegador. Evite que los servidores devuelvan archivos HTML y SVG. Configure una \u0027Content-Security-Policy\u0027 para los archivos multimedia, como \u0027Content-Security-Policy: default-src \u0027none\u0027; base-uri \u0027none\u0027; frame-ancestors \u0027none\u0027; form-action \u0027none\u0027;\u0027."
